Daylight saving time is about to start for Australians in NSW, Victoria, South Australia, Tasmania and the ACT as the clocks move forward this weekend.

During this six-month summer period, the country is divided into five time zones.

Daylight saving time is observed from the first Sunday in October when the clocks are turned forward one hour and ends on the first Sunday in April when the clocks go back one hour.

Most smartphones and computers update the time automatically, but other devices such as analog clocks, alarm clocks, cars, and microwaves must be updated manually.

Some experts warn that the one-hour time change can affect sleep and circadian rhythm for longer than just the hour lost at night.

“Experimental data suggest a cumulative effect of sleep loss that lasts for at least the next week and sometimes longer,” said Dr. Sveta Postnova of the University of Sydney’s School of Physics. 7 News.

A recent survey by ResMed Sleep Health says that one in four Australians is already not getting enough sleep, and nearly half of the adult population has trouble sleeping three or more nights a week.

Clocks advance one hour from 2 p.m., with most smartphones and devices changing the time difference automatically.  Other analog clocks and devices may need to be changed manually

“Spring forward can actually cause significant sleep problems for some of us,” said Dr. Carmel Harrington of ResMed.

“We might get another hour of daylight, but our biological clocks aren’t as quick to adjust and we’ll find it harder to go to sleep that hour earlier and find it difficult to wake up that hour earlier.”

She recommends getting up and going to bed earlier on Saturday to help your body adjust to the time difference and brighten the bedroom for waking up.

dr. Called the world’s foremost authority on daylight saving time (DST), David Prerau believes it can promote better physical health and help reduce street crime.

“(It will) reduce energy consumption, increase economic activity and provide most people with a better quality of life,” Dr. Prerau last year to AAP.

Despite these benefits, some medical experts have called for daylight saving time to be scrapped, fearing that turning the clock forward could have a negative impact on health.

Paul Zimmet, a Melbourne professor at the Monash University Department of Diabetes, expressed concern that health risks associated with losing an hour of sleep when the clocks go forward could be exacerbated by the Covid-19 pandemic.

“In terms of the scientific evidence, which we want to stick to at this point, there are more heart attacks just after daylight saving time, more traffic accidents, and then you have work accidents, car accidents and their implications,” he said. 3AW last year.

Daylight saving time was first introduced in some parts of the world during World War I with the idea that it would save fuel by using less electricity.

Research has shown that the impact of daylight saving time on energy consumption is insignificant.

Experts say daylight saving time can disrupt the sleep cycle for a week or more, with some calling to end the change to daylight saving time due to health concerns linked to the clocks ahead
